Many people around the world often talk about waking up and being unable to move or speak. Here in Japan, it’s often called “kanashibari.” While some cases may be brought about by spirits, the huge majority are caused by sleep paralysis, which is one of the four cardinal symptoms of narcolepsy.

In sleep paralysis, the patient is awake or half-awake, but unable to move. The atonia is similar to the cataplexy that occurs in REM sleep. It is often accompanied by strong fear and a feeling that one can’t breathe. Conditions that cause sleep deprivation or disruption may cause it to occur, so it is not specific for narcolepsy, although it occurs in 1/3 to ½ of patients with the disorder, with the same ratios experiencing hypnagogic or hypnopompic hallucinations.*

睡眠麻痺(かなしばり)

世界中の人々が金縛りのような経験を語る。起きた状態で身体が動けない。場合によって幻覚も見る。まれにこの現象は霊によって起きるかも知らないが、大半は発作性睡眠(ナルコレプシー)の4つの一つの重要症状である睡眠麻痺から起きる。

睡眠麻痺では患者は目が覚めているまたは半分起きているが、動けない。REM睡眠中に起きる脱力発作のアトニー(無緊張)と似ている。強い恐怖感と息の苦しさが伴うこともある。睡眠不足や睡眠障害は原因となることもあるのでナルコレプシー症に対して特異的な症状ではないが、 ナルコレプシー患者の1/3~1/2には起きる。それらの患者のほぼ同じ割合も入眠時幻覚または覚醒時幻覚を経験する。*
